Eutrophication of lakes will significantly increase greenhouse gas emissions

The greening or eutrophication of the world's lakes will increase the emission of methane into the atmosphere by 30 to 90 percent during the next 100 years, say researchers. This increased methane emission is equivalent to 18-33 percent of annual carbon dioxide emissions from burning fossil fuels. Limiting lake greening is important to preserve fragile water supplies and to avoid acceleration of climate change.
